CVE-2026-34079 High · 7.5 CWE-22 Apr 7, 2026

Flatpak affected by arbitrary file deletion on the host filesystem

Flatpak is a Linux application sandboxing and distribution framework. Prior to 1.16.4, the caching for ld.so removes outdated cache files without properly checking that the app controlled path to the outdated cache is in the cache directory. This allows Flatpak apps to delete arbitrary files on the host. This vulnerability is fixed in 1.16.4.

CVE-2026-34078 Critical · 10.0 CWE-61 Apr 7, 2026

Flatpak has a complete sandbox escape leading to host file access and code execution in the host context

Flatpak is a Linux application sandboxing and distribution framework. Prior to 1.16.4, the Flatpak portal accepts paths in the sandbox-expose options which can be app-controlled symlinks pointing at arbitrary paths. Flatpak run mounts the resolved host path in the sandbox. This gives apps access to all host files and can be used as a primitive to gain code execution in the host context. This vulnerability is fixed in 1.16.4.
